An Aspen Center for Physics Public Lecture

Abstract: Quantum mechanics ---with all its oddities--- underpins our our most complete and successful descriptions of nature. Quantum theory describes matter on virtually all scales: from atoms to quarks and from neutron stars to the early universe. (If only gravity could be described by a quantum theory!)

I will discuss experiments with atomic Bose-Einstein condensates: some of the coldest matter in the universe where 100 billionths of a degree above absolute zero is a warm day. By engineering the quantum...

A Pitt/CMU Colloquium 

Abstract: Low-dimensional materials, such as 2D monolayers, 1D nanowires, and 0D quantum dots and molecules, are rich with many-body quantum phenomena. The reduced dimensionality, strong interactions, and topological effects lead to new emergent degrees of freedom of fundamental interest and promise for future applications, such as energy-efficient computation and quantum information. Thermal transport, which is sensitive to all energy-carrying degrees of freedom and their interactions, provides a...
